What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

What are the rules for metal stamping die scrap tube?

The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th

Introduction to the method of evaluating the quality of lubricating oil

  The three major tests for evaluating the quality of lubricants are more critical. As a standard for comprehensively evaluating lubricant quality, countries around the world have basically become consistent, establishing a quality standard consisting of four parts: physical and chemical indicators of lubricants, simulation tests, bench tests, and driving tests. system.

The physical and chemical indicators are the basis. The physical and chemical indicators used to measure the basic performance of lubricants include: kinematic viscosity, low temperature dynamic viscosity, viscosity index, flash point, pour point, sediment, moisture, foam, residual carbon, neutralization value, sulfate ash content And the content of various elements and so on.These physical and chemical indicators are only the basic indicators for measuring lubricating oil. If even the physical and chemical indicators are unqualified, then the following simulation tests and bench tests will not be able to talk about.

The simulation test is the evaluation method. The first is the simulation test. During the research and development of the oil product, the technicians found that the physical and chemical indicators of the oil product cannot explain the problem or reflect whether the mechanical friction pair is easy to use. The main test It consists of the following parts: the coking plate test method and heat pipe test method reflecting the cleanness, dispersion and anti-oxidation of automotive lubricants; the multi-metal oxidation test method and film oxidation test method reflecting the oxidation resistance of automotive lubricants at high temperatures; reflection The speckle test method for the ability of automotive lubricants to disperse sludge; the high-temperature four-ball machine abrasion test method reflecting the anti-wear level of automotive lubricants. These simulation tests can only simply reflect the working conditions of the engine, and cannot simulate the influence of the engine on the performance of the oil, especially under the complex conditions and working conditions. In addition, the simulation test method generally adopts comparatively intensified or generalized test conditions. However, the strengthening will be unrealistic, because in the whole process of the engine operation, various comprehensive factors are combined, which affect the oil’s anti-oxidation, cleaning, dispersion and anti-wear capabilities. It is impossible to perform the simulation test of a single performance evaluation. The method is truthfully measured and evaluated, so the various simulation test methods and their evaluation indicators are basically not reflected in the engine oil specifications.

The bench test reflects the problem more truthfully. In order to truly reflect the use of oil, and at the same time, it can be recognized by the engine manufacturing department. A bench test to evaluate the performance of lubricating oil has been developed.The bench test is to install a representative engine in a test room, perform an evaluation test for a certain period of time under approved or recognized control conditions, and wait for the engine manufacturer to negotiate and determine various performance indicators before the test. After the rack test is completed, it will be judged; observe whether the testable oil product meets the requirements; if the oil product's various judgment indicators are within the limit range, it can be considered that the oil product has been initially approved and obtained the qualification of the type of oil product. certificate.In principle, it can supply the market.After the above three tests, the quality of the lubricating oil can be fully guaranteed to meet the engine oil requirements of various engine manufacturers.
